Vinod Kumar Vavilapalli commented on YARN-1775:
-----------------------------------------------
bq. Also, I wonder if we could make this default to true and simply disable it
when /proc/<PID>/smaps is not present or writable.
Let's wait for a little while to make sure this is reliable enough and working
well. May be, in the 2.5/2.6 releases.
